Installation over ssh (Hint)

[HaioMaio]

Problem install qt over ssh:

$ ./qt-opensource-linux-x64-5.12.2.run --verbose
IFW Version: 3.0.6, built with Qt 5.9.5.
Build date: Nov 13 2018
Installer Framework SHA1: 8b3226b
qt.qpa.screen: QXcbConnection: Could not connect to display 
Could not connect to any X display.

Solution:
make sure on both machines

/etc/ssh/sshd_config

or

/etc/ssh/ssh_config

X forwarding is enabled like:

X11Forwarding yes

I'm quite confident this has nothing to do with Qt.
My bet is that you didn't enable X forwarding when connecting to your remote machine. This is usually done with ssh -X user@machine or ssh -Y user@machine.

The post looked a bit strange to me indeed. But sometimes you cannot are not allowed to edit files in /etc/.
